SPECIFICATION forming part of Letters Patent N 0. 729,88 5, dated. June 2, 1903.

Application filed December 5, 1901. Serial No. 84,845." (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES lvlcsnnnnv, of Pittsburg, Alleghenycounty, Pennsylvania, have invented a new and useful Metallic \Vindow Frame and Sash, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a front elevation, partly broken is designed to provide improved sealing meansbetween the sashes and side frames and between the bottom member of the upper sash and the top member of the lower sash; also to seal the joint between the lower member of the lower sash and the frame and simi larly the joint member between the upper sash and the frame, and, further, to improve the frame construction and the arrangement of the sash-chains.

In the drawings, referring to the form of Figs. 1, 2, and 3, Ishow the frame as composed of a roll having a lower member 2, consisting of a rolled shape having depending side flanges 3 and 4, there being a projecting lip 5 above the flange 4 and an intermediate offset portion 6, extending longitudinally of this member and intermediate of its width. Each side member of the frame is of the hollow-box form shown in Fig. 3, beingpreferably bent up from sheet metal and having an open inner side with flanges 8 8, projecting toward each other. The inner side of this box member is closed by a sheet-metal plate having end flanges 9 9, engaging the outer faces of the box and provided with four reverse-bends 10,forming vertical guideways or pockets for the reception of projecting flanges 11 of the sashes. The side frame member may be stiffened by a partition-plate 12, having a ridged or corrugated portion 13 between the two middle pockets of the closingplate. In my preferred form the sash-flanges 11 are bent integrally from a strip 14,which fits neatly within the side mem ber 15 of the sash. This side sash member 15 has outwardly-projectingflanges 16 and is intermediately bent to form an offset 17, against which the glass is held by a small angle 18. The flanged plate 14: is removablysecured to the side sash member by screws, bolts, or other suitable means, so that by loosening these bolts the sash may be pulled out of the window and the flanged plate 14 removed.

As shown in Figs. 1 and 2, tl1e top and bottom members of the two sashes are formed in the shape of hollow box members bent up from sheet metal. Thelower sash member 19 of the lower sash is provided in its lower face with a groot e in which is secured a yielding gasket 20, which projects downwardly and is pressed against the lower member of the frame when the window is closed. This serves to seal this joint, this sealing action being further obtained by the lips 21, which engage the offset portion .6 l of the lower frame member. The top member of the lower sash and the bottom member of the upper sash are provided upon their adjacent faces with transverse pockets having outer lips 22, the lip upon one member entering the pocket of the other member, thus effectually sealing the joint between the two fastenings. The upper member 23 of the top sash is provided with upwardly-proj ectin lips 24, which enter longitudinal recesses in the rolled channel shape 25, forming the top member of the window-frame, thus sealing this joint of the upper sash.

To provide for the guiding of the chains or cords 26 of the lower sash, Iprovide guideplates 27, which are loosely held within the end portions of the top member of the lower sash by means of screws 28, projecting through slots 29. The outer ends of these plates would thus project through outer slots in this member and are provided with inner recesses 30, through which the cords or chains pass. The plate is provided with an outer lip 31, which engages the top member, as shown in Fig. 5, when the parts are in normal position. When it is desired to remove the lower sash for cleaning or other purposes, the guide-plates are pushed down slightly and then shoved back into the position shown in Fig. 6. The wing-plates 14E of the lower sash are then pushed up into the position shown in Fig. 6, thus leaving the lower sash free, so that it is easily removed.

Instead of forming the sealing wings or lips of a side sash member on a separate plate, I may form them integrally with the side sash member. Thus in Fig. Al I show the side sash member 15 having at both sides projecting wings 11, which enter the pockets 10 of the side frame. In this form also I show curtainguiding recesses formed by outer plates 32, projecting inwardly from the sides of the side frame and coacting with reversely-bent portions to form vertical pockets or recesses, within which curtains are guided. This construction may be used with either of the forms shown in Figs. 3 and 4.

The advantages of my invention result from the eflicient sealing of the window, from the construction which affords easy removal and replacing of the sashes, and from the simplicity of the construction, which can be quickly and cheaply made.

Many variations may be made in the form of the sashes and the frame, the sealing members, and the other parts without departing from my invention, since I claim 1. The combination with a side frame m cmber of sheet metal having reversely-bent portions forming separated pockets, of a side sash member having two projecting flanges, each fitting within oneof said pockets; substantially as described.

2. A side sash member having reverselybent portions forming four pockets, and a pair of sashes each having side members with two projecting flanges parallel with the plane of the sash, each flange entering one of the side frame pockets; substantially as described.

3. The combination with a side frame mem ber of sheet metal having reversely-bent portions forming separated pockets, of awindowsash side member, and a plate detachably secured to said side member and having two projecting flanges, each fitting Within one of said pockets; substantially as described.

4. The combination with a side frame member of sheet metal having reversely-bent portions forming separated pockets, of a side sash member having short flanges, and a plate detachably secured within such flanges and having a pair of projecting flanges parallel with the plane of the sash, each of said flanges entering the pocket of the side frame; substantially as described.

5. A window-frame having a transverse frame member formed of a section of a rolled shape, and sheet -metal side members with bent pockets secured thereto, substantially as described.

6. A metallic window-sash having a transverse member with an adjustable cord-guide substantially as described.

'7. A metallic window-frame having a side member of bent sheet metal with a plurality of separated vertical pockets, a side sash member having projecting flanges entering said pockets, and vertically-extending curtain-guides secured to the side frame members outside the sash-pockets; substantially as described.

I11 testimony whereof I have hereunto set my hand.
